The be quiet! Dark Rock TF 2 exhibits excellent cooling ability and near-silent operation, though it faces stiff competition from its own be quiet! brethren. But as either a performance option where the clearance is the primary limiting factor, or for those who favor downdraft coolers, it’s a solid choice.
Low(er) profile for compact builds
In the world of CPU cooling, be quiet! has been busy lately. We recently tested (and liked) the company’s Shadow Rock Slim 2 budget air cooler. Now the company is adding to its Dark Rock series with a high-end cooler defined as a top flow (downdraft) ‘TF’ model, aptly called the Dark Rock TF 2. Making use of six copper heatpipes and a pair of whisper-quiet Silent Wings 3 fans, be quiet! has performed some metallurgy origami to create its newest stealthy air cooler.
As a dual-heatsink downdraft cooler, the Dark Rock TF 2 utilizes a pair of large+small fin stacks, turned on their side to allow for compact or cramped builds where traditional coolers might exceed installation clearance.
The be quiet! Dark Rock TF 2 ships with mounting hardware suitable for most current Intel desktop sockets and AMD’s AM3(+)/AM4 socket CPUs. All the hardware also arrives dressed in the company’s usual stealth-black color scheme. A 4-pin PWM splitter allows for single-header fan control and a syringe of non-descript thermal paste is included--presumably it’s be quiet! compound.

The Dark Rock TF 2 features a downdraft design, meaning the cooling fans move air down through the cooler toward the motherboard rather than through the cooling tower. Making use of six heatpipes, the large, upper cooling stack evenly distributes heat across the broad face of the cooler directly below the top-mounted fan.
Below, the smaller heatsink sits centered beneath the middle fan, collecting the folded-ever ends of the heatpipes, while providing some surface area to dissipate any heat that doesn’t make its way further up the cooler’s pipes. From one end to the other, the six heatpipes pass between a milled base plate, the mounting block and fixed hardware brace, and wrap up and around to form the folded dual-heatsink downdraft design of the Dark Rock TF 2.
A pair of 135mm fans accompany the Dark Rock TF 2; one is a Silent Wings and the other as a Silent Wings 3 variant. Each are 4-pin PWM managed and rated up to 1400 RPM.
The milled base of the Dark Rock TF 2 is completely flat, leaving ambient light unable to squeeze through between our steel ruler and the cooler’s mounting surface. Beneath the small lower cooling tower, we can see a milled, broad-tooth heat exchanger protruding between the heatpipes and lower tower cooling fins, providing even more surface area for the cooler to utilize.
The milled 40mm x 43mm Dark Rock TF 2 heatsink plate allows for a quality thermal compound, and is quite capable of universal paste distribution over the CPU integrated heat spreader (IHS) during the installation process.
The Dark Rock TF 2 mounts across a pair of stabilizing braces and secures via the two permanently integrated machine screws. Note that the heatpipe cluster has the potential to cause some mounting incompatibility issues with memory DIMMs, depending on motherboard spacing and clearance, making cooler orientation important when choosing how to mount.
Once installed, the cooler sits noticeably lower than most heatpipe coolers, thanks to the downdraft design. This allows the Dark Rock TF 2 to be utilized in system builds with lower cooler clearance. The center-mounted fan slides easily between the small and large cooling stack, and the upper fan rides on a set rubber fan glides. Both get locked down by a set of spring clips to hold them firmly in place.
